Duovent

Duovent

Duovent are heat recovery units designed for economical ventilation of commercial premises, restaurants, shopping centres, etc. The Duovent HVAC units are equipped with an aluminium counterflow heat exchanger with bypass damper or rotary regenerative heat exchanger. They achieve high efficiency thanks to their IE4 EC motors with IP 54 protection. The Duovent air recuperators should always be selected according to specific project requirements and needs. If you are interested in one of these units, please send an enquiry to our email with your requirements or contact us by phone.

The Duovent ventilation units can be supplied in the following versions according to the project requirements:

Compact RV - rotary regenerative heat exchanger, installation in vertical position, on the floor or under the ceiling, positioning of spigots according to specification.
Compact DV - regenerative counter-current exchanger, installation in vertical or horizontal position, on the floor or under the ceiling
Compact DV Top - rotary regenerative heat exchanger with completely separated supply and extract air flows, vertical mounting with spigots on top
Modular DV - regenerative counter-current exchanger, vertical mounting on the floor or roof of the building, positioning of throats according to specification, for high airflows
Modular RV - vertical mounting on the floor or roof of the building, location of the spigots according to specification, for high airflows
Modular XLH/XLHL - rotary regenerative heat exchanger or cross-plate heat exchanger, vertical or horizontal mounting on the floor or roof of the building, location of spigots according to specification, for high airflows

The Duovent ventilation units can be equipped with water or electric heaters, water coolers or direct evaporatorsaccording to project requirements. In addition, they are equipped as standard with easily replaceable filters of class G3 to F9 for both intake and exhaust of contaminated air.

Depending on the design, the Duovent units come standard with Digireg or Minireg digital control.

FGT basic

FGT basic

Thanks to their low construction height, the compact FGT heat recovery units with counterflow plate recuperatorare suitable for installation under the ceiling and are designed for ventilation of office and commercial premises, schools, etc. 

The FGT underceiling ventilation units consist of inlet and outlet panel filters (F7 and M5), counter-current plate recuperator, centrifugal fans with low-energy EC motors, shut-off dampers with actuator and flexible connections. 

The FGT heat recovery units are equipped with a fully interconnected integrated control system including temperature sensors, actuators and S-E3-DSP controller. As standard, the control system provides constant airflow volume CAV control or constant pressure VAV control (optional accessories). Switching between high and low speed can be provided by various sensors, e.g. CO2, humidity, motion, etc.

The FGT underceiling counterflow plate recuperator units are available in 3 sizes for airflow volumes up to 2,500 m³/h.
